Systems and methods for managing shared content based on sharing profiles

ABSTRACT

Content items stored in an online content management service can be organized and shared. Content items can be associated with sharing profiles that include various sharing-specific metadata, such as details of how an item is shared or with whom it is shared. In some embodiments, the metadata stored in the sharing profiles can be used to organize shared content into shared folders automatically and/or to sort a list of content items.

BACKGROUND

This disclosure relates generally to online content management servicesand in particular to managing sharing content stored in an onlinecontent management service based on sharing profiles associated with thecontent.

Online content management services allow users to access and managecontent across multiple devices using the Internet. Online contentmanagement services typically also enable users to share content withother persons, both members and non-members of the online contentmanagement services. In a typical online content management service, auser establishes an account with the service provider and associatesvarious content items with the account. For example, some online contentmanagement services can allow the user to store content items (includingbut not limited to text documents; email messages; text messages; othertypes of messages; media files such as photos, videos, and audio files;and/or folders containing multiple files) and to selectively allow otherusers to access the content items. Content items can be stored in arepository maintained by the service provider and mirrored to orsynchronized with local copies on various user devices.

As more content items are stored in and shared through online contentmanagement services, management of sharing permissions as well asorganization and navigation of content items becomes an increasinglycomplex task.

SUMMARY

Certain embodiments of the present invention relate to organizingcontent items stored in an online content management service based onsharing profiles associated with the content items (including but notlimited to text documents; email messages; text messages; other types ofmessages; media files such as photos, videos, and audio files; and/orfolders containing multiple files). Each sharing profile includescontent item-specific metadata, such as identifiers for who the contentitem is shared with, and any sharing restrictions that are associatedwith the sharing profile. Using the metadata stored in the sharingprofiles, a content management service can enable the user toselectively view shared content items and sort the content items basedon the metadata in the sharing profiles. Content items can be sharedthrough the online content management service to other users and/orgroups. Sharing can be effected by creating a shareable link for acontent item, creating a shared folder, or directly sharing a document.

In some embodiments a sharing summary for a content item can bedisplayed using metadata stored in its sharing profile. A user can makechanges to the sharing summary and those changes can be dynamicallyreflected in the sharing profile. The online content management servicecan automatically organize content items into shared folders based onwho the content items are shared with. A user can manually organizeshared items by joining content items, such as by adding a content itemto a folder or dragging two documents together in a user interface. Whencontent items are joined, the sharing profiles associated with thejoined content items can be updated to reflect the users and/or groupswith which the joined content items are shared.

Using the metadata stored in each sharing profile, content items can besimply and intuitively sorted by the user. This enables the user to keeptrack of, and make changes to, how each content item is sharedefficiently, without requiring the user to navigate to each content itemstored in the online content management service, determine how thecontent item is shared and then decide whether to change how the contentitem is shared. This reduces processing load at the online contentmanagement service. In some embodiments, copies of sharing profiles canbe returned to the user's client device. Using the sharing profiles, theclient device can sort and re-sort the content items as directed by theuser, without further input from the online content management service.This further reduces the processing requirements of the online contentmanagement service and improves the scalability of the online contentmanagement service to by taking advantage of the processing resources ofclient devices.

The following detailed description together with the accompanyingdrawings will provide a better understanding of the nature andadvantages of the present invention.

DETAILED DESCRIPTION

Online content management services can enable users to access theircontent items from any internet-connected device. As described above,these services enable users to organize their content by folder, muchlike traditional file systems. To that end, relatively simple managementtechniques can be provided to organize and navigate a user's content.However, these services can also enable users to share their contentwith other users and groups of users. This adds an additionalorganizational dimension which demands its own management techniques toenable users to quickly and effectively manage their shared and unsharedcontent. Existing content management techniques are inadequate whenapplied to shared content. For example, using existing techniques a usercan identify content items stored in a particular location or having aparticular name. However, with shared content, content managementbecomes more complex. A user may attempt to identify all content itemsshared with a friend, or shared with a project team from work. Thecontent items which match this criteria can be spread across the contentmanagement service among the user's content items. Not only does thiscomplicate the identification of shared content in a useful way, but byextension also complicates changing how and/or with whom the contentitems are shared. As users increasingly rely on these services to storeand share their content, demand increases for more effective managementtechniques that enable shared content to be easily identified, viewed,and otherwise managed.

Certain embodiments of the present invention relate to dynamicallyorganizing content items stored in an online content management servicebased on sharing profiles associated with the content items (includingbut not limited to text documents; email messages; text messages; othertypes of messages; media files such as photos, videos, and audio files;and/or folders containing multiple files). Each sharing profile includescontent item-specific metadata, such as identifiers for who the contentitem is shared with, and any sharing restrictions that are associatedwith the sharing profile. Using the metadata stored in the sharingprofiles, a content management service can enable the user toselectively view shared content items and sort the content items basedon the metadata in the sharing profiles. Content items can be sharedthrough the online content management service to other users and/orgroups. Sharing can be effected by creating a shareable link for acontent item, creating a shared folder, or directly sharing a document.

In some embodiments a sharing summary for a content item can bedisplayed using metadata stored in its sharing profile. A user can makechanges to the sharing summary and those changes can be dynamicallyreflected in the sharing profile. In response to a request to viewcontent items, the online content management service can automaticallyanalyze the sharing profiles of the content items and organize contentitems into shared folders based on who the content items are sharedwith. A user can manually organize shared items by joining contentitems, such as by adding a content item to a folder or dragging twodocuments together in a user interface. Based on the joining, the usersand/or groups with which each content item is shared can be reconciled,and each content item's sharing profile can be updated accordingly.

FIG. 1 shows clients accessing online content management service 100according to an embodiment of the present invention. Online contentmanagement service 100 can include, for example, a file storage service,a file sharing service, a social media service that allows users to postmessages and/or other content, and so on. Online content managementservice 100 can be hosted on servers maintained by a service providerand accessed via network 102, such as the Internet.

Users can access online content management service 100 by operatingvarious clients 110, 112, 114, 116. As used herein, a “client” refersgenerally to a combination of computer hardware and software thatenables a user to interact with online content management service 100.For example, client 110 can be a desktop or laptop computer executing aweb browser (for example, Internet Explorer, Google Chrome, or Safari)that communicates with online content management service 100 using webprotocols such as HTTP (Hypertext Transfer Protocol). Client 112 can bea desktop or laptop computer executing an application program providedby the provider of online content management service 100. In someinstances where the online content management service provides access tofiles, the application program can allow files hosted on a server toappear to exist within a filesystem structure associated with the clientcomputer's operating system. It should be noted that in some instancesthe same client computer can execute both a web browser and a desktopapplication program; accordingly, it is to be understood that a singlephysical device can implement one or more clients.

Other examples of clients include mobile devices, for example, tabletcomputer 114 and mobile phone 116, which can execute applicationprograms (also referred to as “apps”) that communicate with onlinecontent management service 100. At various times, a user can beinteracting with one or more of clients 110, 112, 114, 116.

In some embodiments, online content management service 100 can allowusers to selectively share content items stored in online contentmanagement service 100 with other users, including members andnon-members of online content management service 100. Sharing contentitems (including but not limited to text documents; email messages; textmessages; other types of messages; media files such as photos, videos,and audio files; and/or folders containing multiple files) can beeffected in several ways. For example, a user can select a content itemand specify one or more sharing permissions. As another example, a usercan create a shared folder that includes one or more content items,including nested folders and files. Sharing permissions specified forthe shared folder can be extended to each content item stored within theshared folder.

As yet another example, content items can be shared by creatingshareable links. A user can select a content item and create a shareablelink for that content item. The shareable link can then be sharedthrough various communication media, such as instant message, email,SMS, and other similar channels. Each content item is therefore sharedwith whomever is given the shareable link. In some embodiments, theonline content management service can include an interface for sendingshareable links for content items. A user can provide user identifierscorresponding to those persons to whom the shareable link is to be sent.The user identifiers can include email addresses, membership identifiersassociated with the online content management service, or other similaridentifiers. A shareable link can link to a discrete content item or toa folder. In the latter case, a user following the shareable link canaccess any content items within the folder.

Some embodiments support sharing of content items with groups of usersin addition to individual users. For example, members of a team canshare content items, such as through a shared team folder, to moreeasily collaborate on team-related content items. Each group identifiercan correspond to several user identifiers and the online contentmanagement service can maintain a mapping of each group identifier toits constituent user identifiers. When a content item is shared with oneor more group identifiers, the group identifier mapping can be used toidentify the user identifiers with which the content item is shared.Changes to the membership of a group can be effected by updating thegroup mapping.

Various operations described herein can be implemented on computersystems, which can be of generally conventional design. FIG. 2 is asimplified block diagram illustrating a representative computer system200. In various embodiments, computer system 200 or similar systems canimplement a client (for example, any of platforms 110, 112, 114, 116) ora server (for example, server 200).

In some embodiments, suchintegrated circuits execute instructions that are stored on the circuititself. In other embodiments, processing unit(s) 205 can executeinstructions stored in storage subsystem 210.

Storage subsystem 210 can include various memory units such as a systemmemory, a read-only memory (ROM), and a permanent storage device. TheROM can store static data and instructions that are needed by processingunit(s) 205 and other modules of electronic device 200. The permanentstorage device can be a read-and-write memory device. This permanentstorage device can be a non-volatile memory unit that storesinstructions and data even when computer system 200 is powered down.Some embodiments of the invention can use a mass-storage device (such asa magnetic or optical disk or flash memory) as a permanent storagedevice. Other embodiments can use a removable storage device (forexample, a floppy disk, a flash drive) as a permanent storage device.The system memory can be a read-and-write memory device or a volatileread-and-write memory, such as dynamic random access memory. The systemmemory can store some or all of the instructions and data thatprocessing unit(s) 205 need at runtime.

Storage subsystem 210 can include any combination of computer readablestorage media including semiconductor memory chips of various types(DRAM, SRAM, SDRAM, flash memory, programmable read-only memory) and soon. Magnetic and/or optical disks can also be used.

The computerreadable storage media do not include carrier waves and transitoryelectronic signals passing wirelessly or over wired connections.

In some embodiments, storage subsystem 210 can store one or moresoftware programs to be executed by processing unit(s) 205, such as anoperating system, a browser application, a mobile app for accessing anonline content management service, a desktop application for accessingthe online content management service, and so on. “Software” refersgenerally to sequences of instructions that, when executed by processingunit(s) 205 cause computer system 200 to perform various operations,thus defining one or more specific machine implementations that executeand perform the operations of the software programs. The instructionscan be stored as firmware residing in read-only memory and/orapplications stored in non-volatile storage media that can be read intovolatile working memory for execution by processing unit(s) 205.Software can be implemented as a single program or a collection ofseparate programs or program modules that interact as desired. Fromstorage subsystem 210, processing unit(s) 205 can retrieve programinstructions to execute and data to process in order to execute variousoperations described herein.

A user interface can be provided by one or more user input devices 220and one or more user output devices 225. Input devices 220 can includeany device via which a user can provide signals to computing system 200;computing system 200 can interpret the signals as indicative ofparticular user requests or information. In various embodiments, inputdevices 220 can include any or all of a keyboard, touch pad, touchscreen, mouse or other pointing device, scroll wheel, click wheel, dial,button, switch, keypad, microphone, and so on.

User output devices 225 can include any device via which computer system200 can provide information to a user. For example, user output devices225 can include a display to display images generated by computingsystem 200. The display can incorporate various image generationtechnologies, for example, a liquid crystal display (LCD),light-emitting diode (LED) including organic light-emitting diodes(OLED), projection system, cathode ray tube (CRT), or the like, togetherwith supporting electronics (for example, digital-to-analog oranalog-to-digital converters, signal processors, or the like). Someembodiments can include a device such as a touchscreen that function asboth input and output device. In some embodiments, other user outputdevices 225 can be provided in addition to or instead of a display.Examples include indicator lights, speakers, tactile “display” devices,printers, and so on.

Network interface 235 can provide voice and/or data communicationcapability for computer system 200. In some embodiments, networkinterface 235 can include radio frequency (RF) transceiver componentsfor accessing wireless voice and/or data networks (for example, usingcellular telephone technology, advanced data network technology such as3G, 4G or EDGE, WiFi (IEEE 802.11 family standards), or other mobilecommunication technologies, or any combination thereof), GPS receivercomponents, and/or other components. In some embodiments, networkinterface 235 can provide wired network connectivity (for example,Ethernet) in addition to or instead of a wireless interface. Networkinterface 235 can be implemented using a combination of hardware (forexample, antennas, modulators/demodulators, encoders/decoders, and otheranalog and/or digital signal processing circuits) and softwarecomponents.

Bus 240 can include various system, peripheral, and chipset buses thatcommunicatively connect the numerous components of computing system 200.For example, bus 240 can communicatively couple processing unit(s) 205with storage subsystem 210. Bus 240 can also connect to input devices220 and output devices 225. Bus 240 can also couple computing system 200to a network through network interface 235. In this manner, computingsystem 200 can be a part of a network of multiple computer systems (forexample, a local area network (LAN), a wide area network (WAN), anintranet, or a network of networks, such as the Internet.

Some embodiments include electronic components, such as microprocessors,storage and memory that store computer program instructions in acomputer readable storage medium. Many of the features described in thisspecification can be implemented as processes that are specified as aset of program instructions encoded on a computer readable storagemedium. When these program instructions are executed by one or moreprocessing units, they cause the processing unit(s) to perform variousoperation indicated in the program instructions. Examples of programinstructions or computer code include machine code, such as is producedby a compiler, and files including higher-level code that are executedby a computer, an electronic component, or a microprocessor using aninterpreter.

Through suitable programming, processing unit(s) 205 can provide variousfunctionality for computing device 200. For example, in a mobilecomputing device, processing unit(s) 205 can execute an operating systemand an app to communicate with online content management service 100. Ina desktop computing device, processing unit(s) 205 can execute anoperating system and a desktop application program that presents aninterface to online content management service 100; in some embodiments,this interface can be integrated with an interface to a filesystemmaintained by the operating system. In some embodiments, processingunit(s) 205 can execute a browser application that provides the abilityto retrieve and display content items from sources such as onlinecontent management service 100 (for example, using HTTP or other datatransfer protocols to retrieve and display web pages) and the ability toreceive and interpret user input pertaining to the content items, suchas selection of an item to view, submission of data by the user inresponse to a particular content item (for example, filling out a formon an interactive web page), and so on.

It will be appreciated that computer system 200 is illustrative and thatvariations and modifications are possible. Computer system 200 can haveother capabilities not specifically described here (for example, mobilephone, global positioning system (GPS), power management, one or morecameras, various connection ports for connecting external devices oraccessories, etc.). Further, while computer system 200 is described withreference to particular blocks, it is to be understood that these blocksare defined for convenience of description and are not intended to implya particular physical arrangement of component parts. Further, theblocks need not correspond to physically distinct components. Blocks canbe configured to perform various operations, for example, by programminga processor or providing appropriate control circuitry, and variousblocks might or might not be reconfigurable depending on how the initialconfiguration is obtained. Embodiments of the present invention can berealized in a variety of apparatus including electronic devicesimplemented using any combination of circuitry and software.

As described above, the ability to share content items stored in anonline content management service can lead to more complex contentmanagement challenges. To address these challenges, and enable users toview, organize, and otherwise manage their content items,sharing-specific details for content items can be maintained in sharingprofiles. FIG. 3 shows a sharing profile, in accordance with anembodiment of the present invention. As noted above, each content itemstored in online content management service 100 can be associated with asharing profile that includes sharing-specific metadata about itsassociated content item. Content management service 100 can store thesharing profiles and automatically update each sharing profile aschanges are made by a user and/or based on activity on an associatedcontent item, as described further below. For example, as shown in FIG.3, sharing profile 300 can include sharing status field 302 whichindicates whether the content item is shared. In some embodiments,sharing status field 302 can include a boolean value which representsthe item's state as either shared or not shared. The sharing profile caninclude additional sharing metadata such as sharing mode field 304,indicating how an item is shared, and sharing target field 306,indicating with whom an item is shared.

As described above, content items can be shared in several modes such asby shareable link, shared folder, or directly shared by changing thesharing permissions for a particular content item. As shown in FIG. 3,sharing mode field 304 can include a value which represents how thecontent item is shared. In some embodiments, if a content item has beenshared using more than one mode, sharing mode field 304 can includemultiple values corresponding to each sharing mode. Alternatively,sharing mode field 304 can include a value corresponding to theparticular combination of sharing modes used to share the content item.

In some embodiments, sharing target field 306 can include one or moretarget identifiers. As used herein, a target identifier refers to anidentifier associated with the user and/or group which is the target ofthe sharing. A target identifier can be a user identifier or a groupidentifier. Sharing target field 306 can include a list of one or moretarget identifiers, an object or other data structure which includes theone or more target identifiers, a pointer to an object or other datastructure which includes the one or more target identifiers, or otherindication of the one or more target identifiers.

In some embodiments, the sharing profile can include any sharingrestrictions associated with the content item. For example, temporalrestriction field 308 can indicate a time-based limitation on thesharing of the content item. Such a time-based limitation can include adate and time when the content item will become shared, unshared, or atime period during which the content item will be shared. When a requestis received to download a shared content item, the online contentmanagement service can determine whether the shared content item'ssharing profile includes a temporal restriction and disallow the requestif the temporal restriction is not met. In some embodiments, if thetemporal restriction has expired, the online content management servicecan unshare the content item, such as by disabling a shared link orupdating the sharing status of the content item to indicate the contentitem is not shared.

In some embodiments, geographic restriction field 310 can indicate oneor more geographic regions within which the content item can be shared.For example, content items can be shared with a particular region, suchas a particular country, state, or other political subdivision.Alternatively, content items can be excluded from being shared with aparticular region. Geographic restriction field 310 can includegeographic identifiers corresponding to those regions where the contentitem can be shared or those regions where the content item cannot beshared. In some embodiments, when a request is received to download ashared content item, the online content management service can determinea location associated with the request, for example, based on an IPaddress associated with the request, and compare the request locationwith any locations included in geographic restriction field 310. Theonline content management service can disallow the request if thegeographic restriction is not met.

In some embodiments, the sharing profile can include downloadrestriction field 312 which can define how many times the content itemcan be downloaded. For example, download restriction field 312 caninclude a count, specified by the sharer of the content item or set bydefault. In some embodiments, each time a request to download a sharedcontent item is received, the online content management service candetermine if a download restriction is associated with the sharedcontent item. If a download restriction is set, the online contentmanagement service can determine whether downloads are still availablefor the content item. If it is determined that downloads are stillavailable, the online content management service can allow the requestand decrement the download count. If the download count has reachedzero, the online content management service can deny the request. Insome embodiments, when it is determined that the download count hasreached zero, the online content management service can unshare thecontent item, such as by disabling a shared link or updating the sharingstatus of the content item to indicate the content item is not shared.

In some embodiments, each client device can store copies of sharingprofiles associated with a user's content items. A client device canretrieve updated sharing profiles at default time intervals. In someembodiments, users can define update intervals for sharing profiles. Theuser defined update intervals can be defined globally for all sharingprofiles or can be defined for each content item. In some embodiments,online content management service 100 can push updated sharing profilesto a client device when changes are made to the sharing profiles.

Online content management service 100 can use the sharing-specificmetadata stored in each content item's sharing profile to provide theuser with the ability to organize and view their content items based onthe sharing-specific metadata. FIG. 4 shows a flow diagram of process400 for organizing content items stored in an online content managementservice using sharing profiles, in accordance with an embodiment of thepresent invention. Process 400 can be implemented, for example, ononline content management service 100.

At block 402, online content management service 100 can receive arequest from a client device to display content items associated with auser identifier. For example, when a user logs in to online contentmanagement service 100 from a computer, mobile device, or other clientdevice using the user identifier, and requests to view content items. Atblock 404, online content management service 100 can identify contentitems stored with the online content management service which areassociated with the user identifier.

As described above, each content item stored in online contentmanagement service 100 can be associated with a sharing profile thatincludes sharing metadata about its associated content item. At block406, online content management service 100 can analyze the sharingprofiles associated with the content items, for example to determinewhich content items are shared, with whom the content items are shared,and/or to determine other metadata stored in the sharing profiles. Atblock 408, online content management service 100 can sort the contentitems into a default, or any other predefined, sorted list. For example,the sorted list can be sorted according to whether a content item isshared, or based on content item sharing restrictions. In someembodiments, other content item metadata can be used to sort the list,such as content item name, kind, or modified date. At block 410, thesorted list can be sent to the client device to be displayed. In someembodiments, each content item in the sorted list can be displayed withan indication of whether the content item is shared, based on theanalysis of the sharing profiles.

In some embodiments, online content management service 100 can returnthe sharing profiles associated with the content items to the clientdevice, and the client device can analyze each sharing profile, and sortthe content items into a default, or any other predefined, sorted list.This reduces processing by online content management service 100 andtakes advantage of processing resources at the client device. The clientdevice can display the default sorted list to the user on a displayconnected to the client device. If the user requests to re-sort thecontent, for example by selecting a particular field on the display, theclient device can re-analyze the sharing profiles, re-sort the contentitems into a re-sorted list, and display the re-sorted list. In someembodiments, when the user requests to re-sort the content items, theclient device can automatically request any updated sharing profilesfrom online content management service 100. For example the clientdevice can send a time/date stamp associated with each sharing profileand online content management service 100 can compare the time/datestamps from the client device, to time/date stamps associated with thesharing profiles stored at online content management service 100. Onlinecontent management service 100 can return updated sharing profiles or amessage indicating that all sharing profiles are up to date.

Using the sharing-specific metadata stored in the sharing profilesdescribed above, online content management service 100 can incorporatesharing-based content management features into a user interface,providing users with simple and intuitive access to the sharing-basedmanagement features. FIGS. 5A and 5B show exemplary user interfaces fordisplaying content items stored in an online content management service,in accordance with an embodiment of the present invention. As shown inFIG. 5A, user interface 500 can be displayed on a client device and usedto navigate and manage content items stored in online content managementservice 100. The user interface can display the user's content as shownat 502, sorted according to one or more characteristics of the contentitems. For example, as shown in FIG. 5A, folders and files are organizedseparately and are sorted by name 504. Alternatively, the content itemscan be sorted by kind 506, when they were last modified 508, or whetherthey are shared 510. Each characteristic can be determined based on acontent item's metadata. For example, to determine which content itemsare shared, the online content management system can analyze eachcontent item's sharing profile. User interface 500 can includeselectable icons for uploading new content items 512, creating newfolder 514, creating new shared folder 516, and deleting content items518. User interface 500 can include a search bar 520 to limit or findspecific subsets.

As shown in FIG. 5B, content items can be sorted according to sharingstatus, for example, based on user request. In some embodiments, theuser can submit this request by selecting shared column 510. Onlinecontent management system 100 can then analyze the sharing profile ofeach content item, sort the content items to create a sorted listaccording to the content items' sharing status, and return the sortedlist to the client device for display. As shown in FIG. 5B, Sharedfolder 524 and Document A 526, which were indicated as being shared,have been sorted to the top of the content items.

As described above, a user can organize content items based on whetherthe content items are shared, providing a basic view of shared andunshared content items. However, each content item's sharing profile caninclude additional sharing-specific metadata such as sharingrestrictions and sharing modes. Online content management service 100can use the sharing profiles to provide more detailed views of a user'sshared content items. FIG. 6 shows a flow diagram of a process 600 oforganizing content items stored in an online content management serviceusing sharing profiles, in accordance with an embodiment of the presentinvention. Process 600 can be implemented, for example, on onlinecontent management service 100.

At block 602, online content management service 100 can receive arequest from a client device to display shared content items associatedwith a user identifier. For example, when a user logs in to onlinecontent management service 100 from a computer, mobile device, or otherclient device, that user can be shown, for example, all availablecontent items associated with the user's identifier. The user canrequest to view shared content items, for example, by selecting a“sharing” icon. At block 604, online content management service 100 cananalyze sharing profiles associated with each content item to determinewhich content items are shared. At block 606, based on the request andthe analysis of the sharing profiles, online content management service100 can determine one or more metadata characteristics from the sharingprofiles to be displayed. At block 608, the shared content items can besorted to create a sorted list. In some embodiments, a default sortorder can be predefined, for example, by share type or share expiration.In some embodiments the default sort can be based on non-sharingmetadata such as name or date modified. At block 610, the sorted listcan be sent to the client device for display.

As described above, in some embodiments, each client device can storecopies of the sharing profiles associated with the content items. Thisenables each client device to analyze the sharing profiles and sortand/or re-sort the content items based on requests from the user. Thisoffloads processing from online content management service 100 to theclient devices, taking advantage of processing resources at the clientdevice and generally improving scalability.

Online content management service 100 can provide a user interface thatincorporates access to the more detailed views of a user's sharedcontent items, as described above. These views enable users to morequickly and efficiently manage their content. For example, the views canshow shared content items which have a sharing restriction that is aboutto expire. The views can organize content items by the sharing entitywith which they are shared. This enables the user to see what has beenshared with whom and easily update how the content items are shared.FIGS. 7A-7E show exemplary user interfaces for displaying content itemsstored in an online content management service, in accordance with anembodiment of the present invention. As shown in FIG. 7A, a user canrequest to view shared content items, by selecting a sharing icon 700.The sortable characteristics 702 can be updated to include additionalsharing-specific characteristics such as Restriction and Share Type. Asdescribed above, the share type can indicate by which method a contentitem is shared. For example, in FIG. 7A, both the folder Shared andDocument A are directly shared 704. The user interface can indicatewhether a sharing restriction is associated with any shared contentitems, as shown at 705.

In some embodiments, a user can request different views of sharedcontent items that provide different details of the shared contentitems. For example, different views can be represented as different tabs707 in a user interface, and the user can request a particular view byselecting the corresponding tab. Alternative selection mechanisms arealso possible, for example, by touching and dragging across atouchscreen interface, by selecting icons representing different views,and by other selection techniques. FIG. 7B shows an alternative view ofshared content items. In Restrictions view 706, sharing restrictionsassociated with shared content items are shown as separate sortablecharacteristics. The added sortable characteristics include location708, time 710, and count 712. As shown in FIG. 7B, the restrictions viewcan display all shared content items, not just those content itemshaving a sharing profile associated with a restriction. Alternatively,the restrictions view can be limited to shared content items which havea restriction.

As described above, location restricted sharing can indicate ageographic area or other predefined region to which the content item canbe shared. For example, as shown in FIG. 7B, Shared C is limited toRegion 1. Time restricted sharing can set a predetermined period of timeduring which the item can be shared, such as Document E which is shownas having 54 minutes remaining during which it is shared. Downloadrestricted sharing can set a predetermined number of available downloadsfor a content item before sharing is deactivated. As shown in FIG. 7B,Document F has seven downloads remaining. In some embodiments,restrictions view 706 can dynamically update the sharing restrictions asthey change. For example, the time restriction on Document E canautomatically update as the time counts down, and the download count forDocument F can automatically decrement as download requests arereceived. Sorting by restriction enables users to quickly view whichshared content items are soon to become unshared, for example whichcontent items have a temporal restriction that is about to expire, orwhich content items are nearing their download limits. The user can usethis information to decide whether to request changes to content itemrestrictions, such as extending temporal restrictions or increasingavailable downloads.

FIG. 7C shows target view 714 of shared content items. In target view714, the target identifiers, including both user 716 and groupidentifiers 718, with which a content item is shared are shown assortable characteristics. This enables users to quickly see whichcontent items are shared with which users and groups, and sort thedisplay of their shared content items accordingly. As shown in FIG. 7C,a content item can be associated with multiple target identifiers,including user identifiers and/or group identifiers. In someembodiments, target view 714 can display target identifiers for eachuser and/or group with which a content item has been separately shared.For example, folder Shared A has been shared with Group 1, User 1, andUser 2. In this example, target identifiers included in Group 1 are notdisplayed. Alternatively, in some embodiments, target view 714 candisplay all user and/or group identifiers which have access to a contentitem, regardless of the sharing mode used to provide that access.

FIG. 7D shows link view 720 of shared content items. As shown in FIG.7D, a user can request the link view by selecting links icon 721 or byselecting a Link tab. The link view 720 can include those content itemsfor which shareable links have been created. In the link view 720, theuser can request a copy of the shareable link for a content item by, forexample, selecting a corresponding link icon 722. The copy of theshareable link can be displayed in a selectable format, such as a textfield, and sent to other users and/or groups through a variety ofmessaging techniques. In some embodiments, restrictions 723 associatedwith a shareable link can be displayed along with known targetidentifiers 724 to which the shareable link was sent. In someembodiments, because shareable links can be sent through differentcommunication mechanisms to both members and non-members of an onlinecontent management service, the shown target identifiers can representan incomplete picture of the shareable link recipients. In someembodiments, as known members request the content item using theshareable link, the target identifiers associated with the shareablelink can be updated.

FIG. 7E shows entity view 726 of content items. As shown in FIG. 7E,entity view 726 provides a simplified view of content items 730organized based on the sharing entity 728 with which they are shared. Asused herein, the sharing entity can refer to the particular assortmentof target identifiers, users and/or groups, with which a content item isshared. This view can show which content items are shared with aparticular entity, without changing how or where the content items arestored within the file system. Entity view 726 can show which contentitems have been shared with each user and group, and can show whichcontent items have been shared with different combinations of usersand/or groups. For example, in FIG. 7E, the folder Work and image PhotoA are shown as being shared with Group 1, and the folder Photos andDocuments B and C are shown as being shared with User 1. In thisexample, Photo A is located in the Photos folder, and is thereforeshared with User 1. As such, Photo A is shared with both Group 1 andUser 1, as shown at 732. In some embodiments, as shown in FIG. E, entityview 726 can show the intersection of content items shared with acombination of users and/or groups. Alternatively, a view could beprovided which shows the union of content items shared with acombination of users and/or groups.

In some embodiments, entity view 726 can display content items that havenot been shared. As shown in FIG. 7E, Not Shared 734 can be displayed asthe entity with which the unshared contents are associated. This way,entity view 726 can show a comprehensive view of all of a user's contentitems, rather than just shared content items. Within entity view 726, auser can change the entity with which a content item is shared by, forexample, dragging and dropping the content item between entities. Forexample, to share Document B, which is currently shown as being sharedwith User 1, with another entity such as User 2, the user can selectDocument B and move it to User 2. Entity view 726 can then be updated toshow Document B as being shared with both User 1 and User 2. The usercan also share an unshared content item by, for example, dragging anddropping the unshared content item from Not Shared to the desiredsharing entity. In that case, the unshared content item is no longerdisplayed under Not Shared and is instead displayed under the sharingentity with which it is now shared. Similarly, a shared content item canbe unshared by, for example, dragging and dropping the shared contentitem from an entity with which the shared content item is shared, to NotShared. In some embodiments, when moved to Not Shared, the sharedcontent item can be unshared with all entities with which it was shared.As such, in entity view 726 the formerly shared content item is removedfrom any entities with which it was shared, and the formerly sharedcontent item is displayed under Not Shared. Alternatively, in someembodiments, when moved to Not Shared, the shared content item is onlyunshared with the entity from which it was moved.

Through entity view 726, a user can select a sharing entity name to showonly those content items shared with that sharing entity. For usershaving content items shared with many different sharing entities, or alarge number of content items shared with a particular entity, this canprovide an easier to manage view of content items shared with aparticular sharing entity. In some embodiments, entity view 726 caninclude entities search bar 736. The user can use entities search bar736 to limit the sharing entities shown in entity view 726 to a subsetof sharing entities. In some embodiments, entity view 726 can show theuser's user name as an entity. This enables the user to see thosecontent items which have been shared with the user by different users.By selecting the user's user name, a more detailed view of the contentitems that have been shared with the user can be displayed, includingdetails such as sharing restrictions.

The above-described views of a user's content items enable the user toquickly and intuitively manage their content from a high levelperspective. Sharing of content items can also be managed on a percontent item basis, through an interactive sharing summary. FIG. 8 showsa flow diagram of a process 800 of generating an interactive sharingsummary for a content item, in accordance with an embodiment of thepresent invention. Process 800 can be implemented, for example, ononline content management service 100.

At block 802, online content management service 100 can receive aselection of a content item from a client device. For example, the usercan make the selection through a user interface on a client device. Atblock 804, the selected content item's sharing profile can be analyzedto determine one or more target identifiers with which the content itemis shared. In some embodiments, sharing restrictions can also bedetermined from the sharing profile. At block 806, an interactivesharing summary is generated. The interactive sharing summary caninclude the one or more target identifiers, and/or other information,such as any sharing restrictions associated with the content item. Atblock 808, the interactive sharing summary can be sent to the clientdevice for display.

In some embodiments, online content management service 100 can returnthe sharing profile associated with the selected content item to theclient device, and the client device can analyze the sharing profile todetermine one or more target identifiers with which the content item isshared. The client device can generate the interactive sharing summarybased on the analysis of the sharing profile and display the interactivesharing summary. Any changes made to the interactive sharing summary bythe user, for example adding or removing target identifiers, can beautomatically synchronized with the sharing profile associated with theselected content item stored at online content management service 100.

FIG. 9 shows an exemplary user interface including an interactivesharing summary for a selected content item stored in an online contentmanagement service, in accordance with an embodiment of the presentinvention. As shown in FIG. 9, a user can select content item 900displayed on a client device. Once content item 900 is selected, theonline content management service can analyze a sharing profileassociated with the content item to determine sharing information aboutthe content item, such as target user identifiers with which the contentitem is shared and sharing restrictions. Using this information, theonline content management service can generate interactive sharingsummary 902 for the content item. The interactive sharing summary caninclude sharing permissions 904 that include target identifiers 906 withwhich the content item is shared. Each target identifier can be selectedto dynamically modify the sharing permissions, such as to change asharing restriction or unshare the content item with the targetidentifier. In some embodiments, interactive sharing summary 902 canenable a user to share the selected content item with additional targetidentifiers. For example, as shown at 908, interactive sharing summary902 can include icons that when selected enable a user to share thecontent item with a new user or group identifier. In some embodiments,the interactive sharing summary can be displayed as a sidebar (asshown), a pop-up window, overlay, or other graphical representation andcan vary depending on the client device in use.

As described above, an interactive sharing summary enables the user toview and edit sharing-specific metadata stored in a content item'ssharing profile. This provides users with one way of managing sharingdetails for a given content item. Another method of managing sharingdetails for a content item is to join it with another content item, forexample, by dragging and dropping one content item onto another in auser interface. FIG. 10 shows a flow diagram of a process 1000 ofjoining content items stored in an online content management service, inaccordance with an embodiment of the present invention. Process 1000 canbe implemented, for example, on online content management service 100.

At block 1002, online content management service 100 can receive arequest from a client device to join two or more content items. Forexample, the user can select a first content item and drag and drop thefirst content item onto a second content item. At block 1004, the onlinecontent management service can determine whether to create a new folderbased on the request. For example, if the user selects a document andrequests to join the document with a folder, the online contentmanagement service can add the document to the folder without creating anew folder. Alternatively, if the user selects a first document andrequests to join it with a second document, the online contentmanagement service can automatically create a new folder which includesthe first and second documents. Similarly, if the user selects a firstfolder and requests to join it with a second folder, a new folder canautomatically be created which includes the first and second folders assub-folders. In some embodiments, when a user requests to join a foldercontent item and a non-folder content item, the user can be prompted tochoose whether to create a new folder which includes both content items,or to add the non-folder content item to the folder content item. Atblock 1006, the content items are joined, which can include creating anew folder as described above.

At block 1008, the sharing profiles of the content items are updated.Each sharing profile can be updated depending on how the content itemswere joined and which users and/or groups the content items were sharedwith. If joining the content items results in a hierarchicalrelationship between the joined content items, the sharing permissionsof the hierarchically superior content item can be copied by eachhierarchically inferior content item. For example, if the joining of adocument and a folder results in the document being stored in thefolder, or if a joining of two folders results in one folder beingnested within the other, the sharing permissions of the outermost foldercan be adopted by the content items stored therein. If the joiningresults in a new folder which includes the joined content items, thesharing permissions of the joined content items can be reconciled, andthe sharing profile of the new folder updated to match the reconciledpermissions. In some embodiments, the reconciled permissions canrepresent a union of each content item's permissions. For example, if afirst content item is shared with User 1 and a second content item isshared with User 2, the first and second content items can be joined ina new folder which includes the first and second content items and whichis shared with Users 1 and 2. The sharing profiles of the new folder andthe first and second content items can be updated to reflect the newsharing permissions. Alternatively, the reconciled permissions canrepresent the intersection of each content item's permissions, if thecontent items are shared with at least one common target useridentifier. In some embodiments, the user can be prompted to manuallyreconcile the sharing permissions by defining the sharing permissions ofthe joined content items.

FIGS. 11A and 11B show an exemplary user interface which enables usersto join content items stored in an online content management service, inaccordance with an embodiment of the present invention. As shown in FIG.11A, a user can select first content item 1100 displayed on a clientdevice. Once selected, the user can request 1102 that the first contentitem be joined with a second content item 1104. For example, the usercan drag and drop the first content item onto the second content item.As described above, the result of the joining can vary depending on thecontent items being joined. In the example shown in FIG. 11A, the firstcontent item is a document, and the second content item is a folder. Inthis example, by joining the document and the folder, the document isadded to the folder. In some embodiments, a new folder can be created asa result of the joining and/or a user can be prompted to determinewhether to create a new folder.

FIG. 11B shows a view of the contents of folder Shared B 1104. As aresult of the joining, Document F 1100 has been added to Shared B 1104.Once joined, the sharing permissions of the joined content items arereconciled. Previously, as shown in FIG. 11A, Document F was shared withUsers 5 and 6 and Group 4, while Shared B was shared with User 3. SinceDocument F was added to Shared B, and is therefore hierarchicallyinferior, Document F's sharing profile is updated such that it is nolonger shared with Users 5 and 6 and Group 4, and is instead shared withUser 3 to match Shared B. In some embodiments, an unshared content itemcan be joined with a shared content item. In that case, the unsharedcontent item is shared with the same target identifiers as the sharedcontent item with which it was joined.

As described above, online content management service 100 can providevarious views of a user's content items sortable by sharing specificmetadata stored in sharing profiles. These views do not alter theunderlying file structure of the content management service. In someembodiments, online content management service 100 can enable users tore-sort their shared content based on the sharing specific metadata.FIG. 12 shows a flow diagram of a process 1200 of automaticallyorganizing content items stored in an online content management service,in accordance with an embodiment of the present invention. Process 1200can be implemented, for example, on online content management service100.

At block 1202, online content management service 100 can receive arequest from a client device to automatically organize shared contentitems stored in online content management service 100. For example, theuser can select an “organize” icon displayed in a user interface on aclient device. At block 1204, a new folder can be created for eachsharing entity associated with two or more shared content items storedin the online content management service. As used herein, the sharingentity can refer to the particular assortment of target identifiers withwhich a content item is shared. For example, if a first content item isshared with User 1 and Group 2, the first content item's sharing entityis User 1 and Group 2. Online content management service 100 canidentify each content item's sharing entity based on each content item'ssharing profile. In some embodiments, online content management service100 can iterate through each shared content item to determine how manysharing entities exist among the user's shared content, and to count howmany content items are associated with each sharing entity. At block1204, content items can automatically be moved to the appropriate newfolder, based on their sharing entity.

FIGS. 13A-13C show exemplary user interface 1300 which enables users torequest automatic organization of shared content items stored in anonline content management service, in accordance with an embodiment ofthe present invention. As shown in FIG. 13A, user interface 1300 can beoperable to receive a request to automatically organize shared contentitems. For example, the interface can include selectable “organize” icon1302. The interface can show each user 1304 and group 1306 with whicheach content item is shared. When a user requests that the sharedcontent items be automatically organized, the online content managementservice can identify each content item's sharing entity based on eachcontent item's sharing profile. The online content management servicecan also determine which sharing entities are associated with more thanone content item. For example, in FIG. 13A, Shared A 1308, Shared C1310, and Document F 1312 are each associated with the sharing entityUser 1, Group 1.

In FIG. 13B, a new folder Shared D 1314 has been created for the sharingentity {User 1, Group 1}. The other identified sharing entities {User 3;User 4, Group 1; and Group 3} are each associated with a single contentitem, and therefore new folders for these sharing entities were notcreated. Each content item {Shared A 1308, Shared C 1310, and Document F1312} associated with the sharing entity {User 1, Group 1}, has beenmoved to new folder Shared D 1314. FIG. 13C shows a view 1316 of thecontents of Shared D which now includes content items Shared A 1308,Shared C 1310, and Document F 1312. By automatically organizing contentitems by sharing entity, the online content management service enablesusers to more easily make changes to the sharing permissions of allcontent items shared with a particular sharing entity and provides theuser with a cleaner, more easily navigated view of the user's sharedcontent items.
